Believing that no matter how bad your life is you're still better than someone else by virtue of race becomes more tempting the closer you are to rock bottom.

What data are you basing this claim on?

Well that disagrees with what I have seen. You can say it is correlation and that those are somehow born with the biggot gene can't escape poverty. I think it works the other way, poverty amplifies and accentuates biggotry, rasim, sexims and any other -ism.

This is based on living in other countries, mostly in US though, in both poor and rich communities, some were diverse poor and diverse rich.

Anecdotal evidence is a poor basis for an argument.
